I'm on Win7 x64 so I'm assuming "system32" is still the right place to look.
For C:\windows\system32\1394ohci.sys it says File Version 6.1.7600.20756, Date Modified 7/16/2010 5:02am 1394bus.sys is 6.1.7600.16385 7/13/2009 8:06pm Ohci1394.sys is 6.1.7600.16385 7/13/2009 8:06pm also. -----Original Message----- From: Dave Beumer WØDHB [mailto:[email protected]] Sent: Friday, November 12, 2010 12:52 PM To: 'Drax Felton'; [email protected] Subject: RE: [FlexEdge] Raspy audio -- fixed! If you look at the driver file details; For TI 1394ohci.sys 6.1.7600.16565 dated 4/2/2010 (I actually went to windows/system32/drivers to get details) For Legacy 1394bus.sys 6.1.7600.16385 dated 7/13/2009 Ohci1394.sys 6.1.7600.16385 dated 7/13/2009 Could you check your files and see what dates you have ? -----Original Message----- From: Drax Felton [mailto:[email protected]] Sent: Friday, November 12, 2010 10:29 AM To: 'Dave Beumer WØDHB'; [email protected] Subject: RE: [FlexEdge] Raspy audio -- fixed! The details on the driver say: Driver Provider: Microsoft Driver Date: 6/21/2006 Driver Version: 6.1.7600.20756 Digital Signer: Microsoft Seems weird to me that a signed 64-bit version of this driver would've been available in 2006. I had only these two drivers already on the system. Maybe you need to remove the existing TI one before the update will find it. 1394 OHCI Compliant Host Controller (Legacy) 1394 OHCI Compliant Host Controller -----Original Message----- From: Dave Beumer WØDHB [mailto:[email protected]] Sent: Friday, November 12, 2010 12:17 PM To: 'Drax Felton'; [email protected] Subject: RE: [FlexEdge] Raspy audio -- fixed! Drax I did the same update driver on Win 7 64 and get an older version of the TI 6.1.7600.16565 dated 6/21/2006. Was there anything else you did to get it ? What's the date on your's Thanks Dave -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Drax Felton Sent: Friday, November 12, 2010 10:05 AM To: [email protected] Subject: Re: [FlexEdge] Raspy audio -- fixed! As a follow up to the email below regarding my new Texas Instruments 1394 driver (v.6.1.7600.20756) find: My Flex 5000 has been humming along non-stop since Wednesday. That wouldve been impossible using the Microsoft 1394 drivers. The interesting thing is that I now see infrequent 4000µS DPC Latency spikes that I didnt have before. They dont affect the audio, however. If a driver is going to misbehave then I want it to be the 1394 one taking priority, which seems to be the case. My average DPC latency dropped from a solid 250 µS to the 80 to low 100 range. All good software comes from Texas.

Ive been using the 1394 OHCI Compliant Host Controller (Legacy) under Windows 7 x64 since it happens less often with it. Tonight I got the notion to right click on it in the Device Manager and picked Update Driver Software and then picked the usually worthless option Search automatically. To my surprise it downloaded a new driver that I never had before. The Texas Instruments 1394 OHCI Compliant Host Controller. The specific Unibrain drivers that came with my SIIG card never worked with the Flex at all. I cant wait to see if it works with the actual TI drivers.
